Market share of electric vehicles in the automotive sector is increasing every day that passes by, leading to an increase in popularity for this category of cars. In the current situation, though, electric vehicles are not considered customer friendly: in fact, the main bottleneck for them to reach global diffusion is the short range in terms of km.
The main challenge for current OEM, so, is to increase the distance that an electric vehicle can do on a single charge: in order to do that, two ways are possible:
• Improving the chemistry of the battery
• Increasing the battery size
Of this, the focus of this thesis is on the latter: increasing the battery size, for example by increasing the number of cells that are present in the battery pack, is not something that comes without a cost.
One of the main drawback in doing this is the increasing in charging time for the battery: the risk is that an EV-owner will have to charge the car for a longer time that the one in which the car is being used.
In order to solve this big issue, an increase in charging power is needed, in order to achieve a decrease in charging time. Announcement from different OEM states that the next fast-charger will have a charging power of 150kW. Increasing the charging power leads to an increase of heat losses from the battery, due to its internal resistance, meaning that the temperature increase that the battery will have is not supported sufficiently from the actual cooling system.
So, a new cooling system, with this power requirements as an input must be considered and designed. In order to do that, as a first-step, a methodology for designing the system needs to be developed, and this is the objective of the thesis here presented.
